In the case of COVID-19, SAT can be induced by SARS-CoV-2 infection as well as COVID-19 vaccination. The aim of this study was to present two cases of SAT triggered by mRNA-based COVID-19 vaccines, with special attention paid to the possible significance of HLA-related SAT susceptibility. In our patients, a strong similarity of HLA profiles with regard not only to SAT high-risk alleles but also to other SAT-unrelated ones was observed. The rare phenomenon of SAT occurrence after COVID-19 vaccination can be HLA-dependent and related to a co-presence of HLA-B*35:03 and -C*04:01. Taking into account the similarity of HLA profiles in both our patients, the co-presence of other alleles, such as HLA-A*03:01, -DQA1:01, DQB1*05:01 as well as some of HLA-DRB1, can also play a role. This hypothesis is strongly consistent with autoimmune\/inflammatory syndrome induced by adjuvants (ASIA) being the postulated mechanism of this post-vaccine reaction, as ASIA-related immune reactions are directly associated with HLA-based genetic susceptibility. Further research is necessary to confirm these findings.<\/jats:p>","DOI":"10.3390\/vaccines10020280","type":"journal-article","created":{"date-parts":[[2022,2,13]],"date-time":"2022-02-13T20:35:28Z","timestamp":1644784528000},"page":"280","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Significance of HLA Haplotypes in Two Patients with Subacute Thyroiditis Triggered by mRNA-Based COVID-19 Vaccine"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2910-7691","authenticated-orcid":false,"given":"Magdalena","family":"Stasiak","sequence":"first","affiliation":[{"name":"Department of Endocrinology and Metabolic Diseases, Polish Mother\u2019s Memorial Hospital\u2014Research Institute, 281\/289 Rzgowska St., 93-338 Lodz, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katarzyna","family":"Zawadzka-Starczewska","sequence":"additional","affiliation":[{"name":"Department of Endocrinology and Metabolic Diseases, Polish Mother\u2019s Memorial Hospital\u2014Research Institute, 281\/289 Rzgowska St., 93-338 Lodz, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8748-3337","authenticated-orcid":false,"given":"Andrzej","family":"Lewi\u0144ski","sequence":"additional","affiliation":[{"name":"Department of Endocrinology and Metabolic Diseases, Polish Mother\u2019s Memorial Hospital\u2014Research Institute, 281\/289 Rzgowska St., 93-338 Lodz, Poland"},{"name":"Department of Endocrinology and Metabolic Diseases, Medical University of Lodz, 281\/289 Rzgowska St., 93-338 Lodz, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,2,11]]},"reference":[{"key":"ref_1","first-page":"489","article-title":"Clinical characteristics of subacute thyroiditis is different than it used to be-current state based on 15 years own material","volume":"39","author":"Stasiak","year":"2019","journal-title":"Neuro Endocrinol.
